Materials Data on NpCd11 by Materials Project

Abstract

NpCd11 crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Np is bonded in a 12-coordinate geometry to twenty Cd atoms. There are a spread of Np–Cd bond distances ranging from 3.55–3.86 Å. There are five inequivalent Cd sites. In the first Cd site, Cd is bonded in a cuboctahedral geometry to twelve Cd atoms. All Cd–Cd bond lengths are 3.13 Å. In the second Cd site, Cd is bonded in a 6-coordinate geometry to three equivalent Np and six Cd atoms. There are three shorter (2.93 Å) and three longer (2.94 Å) Cd–Cd bond lengths. In the third Cd site, Cd is bonded in a distorted q6 geometry to two equivalent Np and eight Cd atoms. There are two shorter (2.93 Å) and four longer (3.00 Å) Cd–Cd bond lengths. In the fourth Cd site, Cd is bonded in a 10-coordinate geometry to one Np and nine Cd atoms. All Cd–Cd bond lengths are 3.13 Å. In the fifth Cd site, Cd is bonded in a 10-coordinate geometry to one Np and nine Cd atoms. There are four shorter (3.00 Å) and four longer (3.13 Å) Cd–Cd bond lengths.
